This allows you to reduce the number of troop required. Cut the power, since most of the electricity generated is outside the city limits. Use image enhancement, FLIR and drone patrols, and you can see anything in the dark and kill it. Now, you can choke off any food or water going into the city. There is perhaps five days food, 24 hours of water, city wide, in stores and warehouses. Two weeks before surrender? A month until cannibalism?
I'm just a dumb ol' conservative. Imagine the super brains in the White House, and the Progressive faction in the Pentagon. These are the same guys that would claim, today, that the Ardennes Forest does not permit armored attacks...
I think a lot of freepers confuse being at war with FedGov and having martial law imposed by the military. There is a big difference and many do not understand or can keep up with the conversation.
